Hello,

I am new to Kincony boards and am having a problem. I am probably making a small mistake somewhere.

I have several Kincony A16 Rev. 1.6.

I am flashing with the “ESP-Flasher-Windows-x64” program and using the firmware from the first page (https://www.kincony.com/forum/attachment.php?aid=642).

After flashing, I adjust the “PCF8574” parameters as shown in the images on the first page. I have also tried inverting and not inverting.

However, when I switch the outputs via the WebUI, the relays on the board do not switch. There is no sound, and I have also measured it.
The inputs work.

I have also reflashed several times.

I have also attached a picture of my setup.

Can someone please help me?

you have not connect with DC terminal, see the photo, you need to add the RED cable from power supply.

I flashed the board with this firmware. Everything is working properly. But in this firmware there is no possibility to connect DS18x20 sensors. Is there any way to add them? Maybe using templates?

why can't use DS18B20? if you downloaded KCS v2 firmware, just add DS18B20 in "sensor" webpage.

Sorry, I expressed myself inaccurately. It means Tasmota firmware.  It does not have DS18B20 in the sensors section.
Tasmocompiler usage was  unsuccessful.
Only your program from 2022 is suitable. But it have not  DS18B20  support.

you can compile tamota firmware to enable ds18b20.
